What is the purpose of control structures in JavaScript?

Control structures in JavaScript serve the essential purpose of controlling the flow of the program. These structures, such as conditional statements (like if-else) and loops (like for and while), determine the path that the program takes when it is executed. For instance, a conditional statement allows the program to execute certain blocks of code only when specific conditions are met, enabling dynamic responses based on input or other factors. Loops facilitate the repetition of code execution, enabling tasks to be performed multiple times without the need for redundant coding. This dynamic control over the program's flow is fundamental to implementing logic and creating interactive applications. The ability to dictate how and when certain lines of code are executed is what makes control structures a critical component in JavaScript programming.
